SEALING COMPOSITION EGR EADIATGRS.

' nseaaea,

Ho Drawing. Application filed. June 2,

To all whom it may concern: e

Be it known that I, GEORGE E. PERKINS, a citizen of the United States, residing at Atkinson, in the county of Henry and State of Illinois, have invented certain new and useful Improvements in Sealing Composition for Radiators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a compound for sealing cracks or breaks that may arise in radiators, particularly of combustion gas engines of automobiles, although ,it may be used in other types of radiators or other chambers where it is desirable to close fractures or breaks that would result in leakage.

The object is to provide a composition which will float and be carried by the circulating fluid or agent into contact with the three and one third per cent; flaxseed meal,

sixty three and two thirds per cent; lampblack, one er cent; and guaiac resin, two per cent. he composition is prepared by first pulverizing the turpentine resin and the guaiac resin and then placing the two pulverized resins in a suitable mixing machine in which is placed the flax seed meal, the several ingredients being thoroughly mixed with one another; the lamp black is then added and all the ingredients thoroughly mixed, the mixing operation tendin to bring the particles of oil in the flax see meal to the surface of the particles and into contact with the lamp blacli. When this composition is put into the circulating fluid of the radiator the fluid carries the compound with it, the oil of the meal serving to float the particles of meal and resins and lam black so that the composition will be carried by the circulat- Specification of Letters Patent.

and will enter any breaks or cracks in said surface and close the same. The heat of the circulating fluid melts the particles of resin and the same together with the meal and lamp black are carried by the fluid and the pressure within the radiator forces the composition into the breaks or cracks and closes the same against leakage. penetrates the breaks to points that might not be reached by some particles of the meal and the resins melted by theheat cause the particles to adhere to the walls of the crevices and form a filling to efiectively close the same. The guaiac resin is more soluble than the other ingredients and renders the turpentine resin more plastic than turpen tine resin by itself and also renders the composition less brittle when cooled, so that there is produced a sealing composition that is elastic, penetrating, possessing strong adhesive qualities, and that is readily floatable or buoyant in the circulating fluid without undue precipitation in conveyance throughout the chamber in which the fluid circulates. The composition may also be effectively used without becoming brittle even when denatured alcohol is used in the circulating fluid to prevent freezing in the winter season.

I have given the proportions of the different ingredients which I have found-to give the best results under varying conditions but changes can be made in the proportions and material benefits of the composltion still be derived.

Having described my invention and set forth its merits what I claim is:

1. The composition for sealing crevices in radiators consisting of turpentine resin, guaiac resin, flax seed meal, and lamp black, the guaiac resin being in a smaller per cent. than the turpentine resin and flax seed meal.

2. The composition for sealing crevices in radiators containing turpentine resin, aiac resin and flax seed meal, the flax see meal being in a greater per cent. than the other ingredients and the guaiac resin in a smaller per cent. than the turpentine resin.

In testimony whereof I aflix my signature in presence of two witnesses.
